worldcat.org

WorldCat is a union catalog that itemizes the collections of 17,900 libraries in 123 countries and territories that participate in the OCLC global cooperative. It is operated by OCLC, Inc. The subscribing member libraries collectively maintain WorldCat's database, the world's largest bibliographic database. OCLC makes WorldCat itself available free to libraries, but the catalog is the foundation for other subscription OCLC services. WorldCat is used by the general public and by librarians for cataloging and research. More information...
